1 month old baby

My 1 month old baby can hold his head up really well. Especially when I am burping him over my shoulder he can hold his neck up pretty well. I obviously am cautious about it.

My aunt (not very close with her) and I only see her once in a blue moon said something about how strong he is. She said “at only 1 month he should be that strong- there’s something wrong if he can do that”

I didn’t think about it that way but now I’m worried. Being a first time mom.

Is this normal or?
